My invention relates to a hand-truck or trolley of the kind which willtake up and deposit a container for the load by a simple movement of itshandle and more particularly to a two-Wheeled truck in which a framebeing rigidly connected with a handle is tiltably mounted on the Wheels.

rl`he main object of my invention is to avoid a swinging motion ofthecontainer 3o on the truck frame and a turning moment exerted by the loadon the handle during the travel of the truck. Another object of myinvention is to facilitate'the taking up of the container by lifting itstepwise.

l'n the drawing two preferred "embodiments of my invention areillustrated.

Fig. l is a side elevation showing the two- Wheeled trolley in theposition in Whichthe raising of the container is initated.

Fg. 2 is a side elevation showing the container partly7 raised bytilting.

Fig. 3 is a side elevation showing the con` tainer fully raised andsuspended by the frame of the trolley.

lFig. 4 is a plan view of a part of the aggregate consisting of thetrolley and the container. A

Figures 5, 6- and 7 are side elevations of a modification, such figurescorresponding 3o with the Figures 1, 2 and 3 respectively.

Fig. 8 is a plan view of a part of the modiiication.v

According to Figs. 1 4 a is a box-like container on'each side of whichtwo cylindrical projections b and c are provided. -h is a U-shaped framewhich is connected with axles '1,' ofwheels c and with a handle (l. Thearrangement of the projections b and c is symmetricalwith respect to avertical 40 plane dividing the container into equal portions in frontand rear and passing through the axis of the wheels, when the containeris suspended at its projections b and c. In the frame h supportingsurfaces in the form of notches are provided which correspond With theprojections b and c on each side of thecontamei` a. As soon as thehandle d with the frame h is tilted into :the position shown in Fig. 1,one of the notches on4 each side of the frame will engage theprojection-- 300,347, and in Germany February 1, 192s.

b on each side of thefcontaincr. lWhen depressing the handle d with theframe h, the container will firstbe partly raised by tilting as shown inFig. 2, whereupon the other of the notches on each side of the framewill engage the projection c on each side of the container, as shown inFig. 3 according to which the container is fully raised'and suspended bythe frame h of the truck. The depositing of the container is effected byreversing the manipulation.

As the arrangement of the projections b and c is symmetrical withrespect to a vertical plane dividing the container into equal portionsin front and rear and passing through the axis of the wheels, when thecontainer is suspended at its projections .b and c no turning moment isexerted on the handle'bythe load. .Also swinging motions of thecontainer on the trolley are avoided.

In the embodiment shovvnA in Figs. 5 to 8 the elements and parts a, b,c, d, e, h and z' correspond with those elements and parts designated inFigs. 1 to 4 by like referenceletters. According to Figs. 5 tol 8additional projections f and g are provided on each side of thecontainer, and an additional notch is provided on each side of theyframe 1-,'such notches being adapted to engage the projections f or theprojections g, the latter in the case that the projections g come intothe positionof thel projections f. Thevprojections f or g and thecorrespondingnotches in the frame only serve for .initiating the tiltingand partial raising of the container, as shown in Fig. 5. When .furtherdepressing the handle d with the frame h, the projection f comes out ofengagement with the corresponding notch, and in the same .time theprojection b is engaged by the corresponding notch, as shown in Fig. 6.At the end of the manipulation also the projection c' isengaged by thecorresponding notch, so that the Vcontainer is only suspended at itsprojections b and c, whereas the projections lf or g remain inoperativeduring the travel of the truck.

What I claim is:

1. In a truck the combination of ahandtrolley comprising a pair ofwheels and a U-shaped frame being tiltably mounted on said wheels andrigidly connected with a handle, said frame having on each side notchesadapted to be raised and lowered by depressing and lifting the handle,with a separate container having on-each side cylindrical projectionsadapted to be engagcd by said notches for raising the container clear ofthe floor and suspending it, at least one of said cylindricalprojections and the cooperating notch on each side of the container andthe trolley-frame serving only for initiating the raising motion, suchparts being out of engagement with one another, while the container isoperatively suspended. v i

2. In a truck the combination of a handtrolleys substantially comprisinga pair of wheels and a frame tiltably mounted on said wheels and havingon each side a plu,-

lality of supporting surfaces adapted to be raised and lowered bytilting the frame,

with Aa separate container having on each side a plurality ofprojections adapted to be engaged by said supporting surfaces ofthe'hand-trolley. for raising the container clear of the Hoor andsuspendin it, two of said projections on each side o the container ,andthe corresponding supporting surfaces of the trolley being operativeduring the travel of the truck, the4 said two projections on each sideof the .container being arranged symmetrically with respect of avertical plane dividing the container into equal portions in front andrear and passing through the axis of the wheels when the container is inits operatively suspended on each side of the container andr thecorresponding notches of the trolley being operative during the travelof the truck, the said two cylindrical projections being arrangedsymmetrically with respect of a verbe raised and lowered by tilting theframe with a separate container havlng on each side a plurality ofprojections adapted to be engaged by said supporting surfaces for'raising the container clear ofthe fioor and suspending it,--theoutermost pair of projections and cooperative supporting faces servingonly for raising apart of the container Weight by initiating the tiltingaction, the whole container weig t being supported by two pairs ofprojections on the com letion of tilting action, so that the verticalplane dividing the container in equal portions passes through the axisof the wheel-s.
